If you look for a well-defined and rational response, I don't think there's one.
Anyway, I'd like to say that people is being too cynical about this. There has been, and there are right now, many efforts in Europe for supporting and integrating non-european refugees and inmigrants.
This "oh look, they care because they're white", well, there's a lot of selection bias right there, and I don't think we should be sorry to care about people we feel it's the same to us.
There has been hundreds of thousands of non-european people inmigrating to Europe for years, but somehow we're hypocrites now.
